【 摘 要 】

Large numbers of inhabitants in a dense area require land coverage for sheltering purposes. The anthropogenic heat emission potentially reduces ventilation of urban areas and significantly brings changes in air temperature. This study is aimed at finding the correlations between urban form and the alteration of urban microclimate in different land-uses. This study has been carried out in Bandung, Indonesia, in its educational, high dense settlement and industrial areas, covering around 37 ha each. The measurement of air Temperature (Ta), globe Temperature (Tg) and wind speed (Va) describes mean radiant Temperature (Tmrt), which gives direct impact on the quality of outdoor spaces in urbanized areas. 3D modeling based on a Sketch-up and introducing Chronolux, as a simple model has given a description of the Sky View Factor (SVF) in urban form. Urban form that is presented by building coverage is giving significant impact to Tmrt as shown in high-dense settlement with R = 0.82. Tmrt and SVF at all study areas show positive correlations, eventhough not in significant values where at educational area R = 0.029; meanwhile at high-dense settlement R = 0.2 and finally at industrial area R = 0.28.
